The purpose of this study was to investigate the effect atmospheric pressure plasma application on water contact angle (CA) zirconia ceramics. Two ceramics (Katana, Kuraray Noritake Dental and Lava, 3 M ESPE) were used test treatment (SAP, surface) with argon gas for one minute (1 L/min). To measure CA, a drop placed surface, which observed under optical microscopy, images calculate CA (n = 5). dynamic behavior surface wettability analyzed by collecting data over 70-hour period. two-way...
Abstract Objective This in‐vitro study assessed the influence of two intraoral scanning (IOS) protocols on accuracy (trueness and precision) digital scans performed in edentulous arches. Methods Twenty‐two abutment‐level master casts arches with at least four implants were scanned repeatedly five times, each different protocols. Protocol A (IOS‐A) consisted arch before inserting implant scan bodies, followed by their insertion its subsequent acquisition. B (IOS‐B) bodies inserted from...
The objective of this study is to evaluate the effect a cleaning agent and priming on bond strength (BS) resin cement (RC) zirconia ceramics after 24 h 1 year water-storage.Fifty-six Katana 56 ZirCAD ceramic plates were prepared each brand was divided into four groups (n = 14): (1) untreated; (2) treated with Ivoclean agent; (3) Monobond Plus coupling (4) + Plus. Cleaning agents applied following manufacturers' instructions. RC manipulated, inserted tubes (0.75 mm diameter/1 height) that...
Purpose To evaluate the influence of different surface treatments two CAD/CAM glass ceramics on topography, shear bond strength composite cement, flexural strength, and elastic modulus. Materials methods Two were evaluated: lithium-disilicate (LDS) zirconia-reinforced lithium silicate (ZLS) ceramics. Glass sintered surfaces sandblasted (SBL) or etched with 9% hydrofluoric acid for 10 s (HF10), 20 (HF20) 30 (HF30). The treated analyzed using scanning electron microscopy (n = 3) to...
Objective: to evaluate the effect of aluminum oxide sandblasting (AOS), argon plasma application (APL) and their combination (AOS+APL) on shear bond strength (SBS) dual-cure resin cement (Panavia F 2.0, Kuraray Noritake) two zirconiabased ceramics (Lava, 3M ESPE Katana, Noritake). Material Methods: One hundred twenty zirconia plates (13 mm in length X 5 width 1 thickness) were prepared treated according following treatments: 1- AOS, 2- APL,3- AOS+APL 4- no treatment (control). After...
To evaluate the effectiveness of nonthermal atmospheric plasma (NTAP) and priming on shear bond strength (SBS) a resin cement to two zirconia ceramics after 24 hours 1 year water storage.A total 120 plates (9 x 7 2 mm) were obtained from types (Katana, Kuraray Noritake; ZirCAD, Ivoclar Vivadent) randomly divided into 12 groups (n = 10 each). Zirconia ceramic submitted following treatments: (1) untreated (control); (2) treated with ZPrime Plus (Bisco Dental) primer; (3) NTAP (Surface Plasma...
Abstract Objectives To evaluate the effect of atmospheric pressure plasma (PLA), sandblasting (SAN), silanization (SIL) and hydrophobic bonding resin (HBR) on micro‐shear bond strength (MSBS) fresh nanofilled (NF) or microhybrid (MH) composites to water‐aged composite. Materials methods NF plates were fabricated stored in distilled water for 4 months. The aged assigned groups ( n = 6): 1‐ untreated; 2‐ SAN + SIL HBR; 3‐ 4‐ PLA 5‐ 6‐ 7‐ PLA. Two composite cylinders constructed each plate with...
Sinus floor elevation with the lateral window approach has proven to be an effective treatment modality for vertical bone augmentation in posterior region of maxilla. The simultaneous implant placement during procedure can achieved if enough remaining height is available obtain primary stability. However, proper identification maxillary sinus boundaries demarcation along membrane protection challenging. This clinical report demonstrates a novel technique using 3D modified...
The aim of this retrospective clinical study was to compare the accuracy static Computer-assisted implant surgery (sCAIS) in posterior single edentulous patients using different surgical guide designs.Thirty-seven partially with a total 54 implants were included study. Seventeen Group 1-Unbounded Tooth-Mucosa Supported; 18 2-Unbounded Tooth and 19 3 (Control)-Bounded Supported. All treated fully guided corresponding guide. Discrepancies between pre-planned post-operative position...
To review the factors that affect ability to deliver a CAD/CAM implant-supported provisional restoration designed from virtually planned implant position prior surgical placement with static computer-assisted surgery (sCAIS).Data were collected on patients treated single-tooth treatment in which CBCT was combined intraoral scans and imported into virtual planning software. A synchronization tool established connection between software CAD software, where digital diagnostic tooth arrangement...
To evaluate the flexural strength (FS) and modulus (FM) of a commercial 3Y-TZ0P ceramic after artificial aging either without or with two application times non-thermal plasma treatments (NTP). In addition, changes in crystalline phase transformation surface nano-topography NTP application, during different periods, were evaluated. Ninety 3Y-TZP bars (45x4x3 mm) made for FS FM testing, assigned to nine groups (n=10): no NTP/no (Control); NTP/4h aging; NTP/30h 10s 60s aging. Artificial...
The aim of this study was to evaluate the bond strength (BS) a resin cement two zirconia ceramics, after surface treatment with non-thermal plasma (NTP) and sandblasting aluminium oxide abrasive.Sixty Lava 60 Katana Zirconia plates were cut accordingly required dimensions randomly divided into 8 groups.For all specimen, cylinders made using 1,4 mm diameter x 1 height matrix.The tested 24 hours, shear test device.Data analyzed by 2-way ANOVA Tukey's (5%).
